Either the End or Center Peripheral discharge rod mill can be used for wet or dry grinding. Whatever the type, the rod mill is used to produce a coarse product, whereas the ball mill is used to produce a finer product. Should a ball mill grind be required, the relationship of the length to the diameter of the mill is important. Feed and product
Rod mills are grinding machine which employ high carbon steel or special steel rods of nearly the same length as that of the drum, in place of steel balls in ball mills. Rod mill products are generally coarser than those produced in a ball mill, and rod mills are well suited to handle coarser feed and to control the top size of the product
If N is taken to be the gross mill power, values of the factor c in wet grinding mills will be. rod mills 1/1800 ball mills, grate discharge 1/1200 ball mills, overflow type 1/1470 pebble mills 1/1200. W for rod and ball mills shall be taken as the weight of the rod or ball charge, i.e. the weight of the pulp is to be ignored. For pebble mills

The mills can be used either for dry or wet, rod or ball grinding. By using a separate attachment the discharge end can be changed so that the mills can be used for peripheral instead of overflow discharge. The lining is generally made as a plate of wear resistant steel with welded on lifters. The heads are bolted onto the shell which
Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles.  But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Ball mill is the most widely used kind of grinding equipment. Ball mills are widely used in various types of ores' benefication, electricity, cement and chemical industries. With high comminution ratio,it can carry out dry or wet pulverizing and can meet demand for sustainable large-scale production. The most widely used in the
The End Peripheral Discharge Rod Mill is designed to produce a minimum amount of fines when grinding either wet or dry. Material to be ground enters through a standard trunnion and is discharged through port openings equally spaced around the mill periphery. These ports are in a separate ring placed between the shell and the discharge head.
When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the
Introduction to Rod Mill. Rod mills, also named rod grinders, are available in dry and wet types. Customers can choose anything they like according to actual conditions. The company adopts the advanced controllable materials feeding in and discharging technology and installs appropriate grinding rod depending on the actual materials changing

Our Rod Mills are available in multiple diameters to fit the needs of your operation. Grinding, primarily by attrition, Rod Mills require comparatively low levels of power to operate. Rod Mills can be either wet or dry designs. Once replaced by AG and SAG mills, Rod Mills have had
Ball mill, an energy-saving grinding device, is widely used in mineral processing, building materials and chemical industries. Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.
The Rod Mill is the same as the Ball Mill in the construction and available to both of wet and dry processing. Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill. In other words, the Rod Mill gives impact on and grinds coarse particles
Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh). Rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and construction materials industries, mainly suitable for grinding various ores
The factor CF is the correction for non-standard conditions including wet open circuit, wet closed circuit, wet and dry grinding, over size feed and under size grinding. Mill Power Draw The motor power draw required to turn a mill from rest to the operating speed includes the energy required for the initial starting torque and mechanical arrangements to rotate the mill.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh). Rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and construction materials industries, mainly suitable for grinding various ores and rocks and artificial sand-making.
The working principle of dry rod mill is the same as that of wet rod mill. The gearing-down of electrical machinery and peripheral gear drives the cylinder body rotates. The appropriate steel rod is installed in the cylinder body as the grinding medium. Under the action of centrifugal force and friction force, the grinding medium is lifted to a
Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.

Wet grinding rod mills are normally used in the mineral processing industry. Dry grinding is used in some areas; however, it is confronted with problems and should be avoided except where absolutely necessary. Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses
The lattice ball mill has a spiral structure inside the feed port, and the feed port is a common liner (end liner) without a bore. The cylinder body is an ordinary cylinder liner, and the discharge head is a lining plate with a boring hole (the rafter plate), and the inner spiral direction of the discharge port is consistent with the feed port.
Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable proportion.Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder.
